A single-phase fully controlled bridge circuit with R-L load is used to obtain the regulated dc output voltage. The RMS value of the ac input voltage Vs and the firing angle at 60°, so that the load current is I0.
The ratio of the average output voltage of the converter when a freewheeling diode is connected across the load to the average output voltage of the converter without any freewheeling diode is ________ (up to two decimal places)Enter numerical value using the virtual keypad. Round off where necessary.
